Every spy movie ever made

even before the technology was readily available) features at least one fingerprint security device. They are nearly impregnable, able to open only when the correct user displays his fingerprint for scanning and confirmation. Heroes rarely find themselves befuddled by them, and yet these locks continue to create a sense of invulnerability among the common layman.

Fingerprint technology, although the darling of Hollywood spy films, is quickly becoming easily accessible by the general public. Online companies likeFingerPrintDoor- Locks.com sell easy-to-use and easy-to-install locks that even the techno-unsavy could easily set up and have ready within 15 minutes. Once properly set up, the door locks open with either coded access, a manual key or through biometric technology. Just hold your thumb or finger over the scanner and Presto! - the lock opens.

Fingerprint locks start at around $300 but can climb in price into the thousands. Although pricey for your everyday doorknob and lock system, they offer an added bonus that other locks do not. While losing your key would be detrimental if you employed a standard doorknob, with these it's no worry. Most require no computer access and can be programmed with over 100 fingerprints right on the device. Give access to your entire family and never worry about your children losing their keys and getting locked out again. Taking your keys on short trips to the neighbors or down the street is no longer necessary, either.

These locks, however, are not simply for exterior doors. Use one on an interior closet to create an impregnable safe. Store firearms inside to prevent access to children, or hide away your valuables to prevent theft.

Set the alarm to silent and the unit simply records at what time the lock was broken. At only $10 and available through ThinkGeek.com, this novelty may not provide the security of a fingerprint lock but makes up for it in fun.
